PIC24HJ16GP304-I/PT - 40 MIPS 16-bit MCU 16KB Flash 44-TQFP | Microchip
MPN: PIC24HJ16GP304-I/PT ✓ Hoạt độngPIC24HJ16GP304-I/PT Tóm tắt
A 16-bit microcontroller is a single-chip processor that combines a 16-bit CPU datapath, on-chip Flash, SRAM, and a rich set of peripherals in a single IC, sitting in the hierarchy MCU -> microcontroller -> embedded processor -> semiconductor. The PIC24H family targets high-speed, repetitive-computation and closed-loop-control applications that exceed the performance envelope of 8-bit MCUs while remaining lower cost and lower power than 32-bit ARM Cortex-M parts. The PIC24HJ16GP304 is the 16 KB Flash / 28- to 44-pin variant of the dsPIC33F-compatible PIC24HJ16GP302 family.
Key differentiating specifications include 40 MIPS sustained throughput from a 20 MHz external crystal (4x PLL), 16 KB self-programmable Flash with ECC, hardware CRC engine, JTAG boundary scan, and five 16-bit timers. The PPS fabric allows nearly every digital peripheral to be routed to a wide selection of physical pins, simplifying PCB layout and reducing muxing constraints. Two UART/SPI/I2C modules, two CAN 2.0B controllers, and a 6-channel PWM/OC make it well suited to multi-protocol industrial nodes.
The architecture uses a 24-bit fixed-width instruction set with 16-bit datapath registers, separate program and data buses, and a 17-bit x 17-bit hardware multiplier that delivers single-cycle MAC operations critical for digital signal processing routines. A two-level pipeline and deterministic interrupt response free of Flash wait-state stalls let the device sustain real-time control loops at the 40 MIPS ceiling without jitter.
Typical applications include industrial motor control, sensor data acquisition nodes, automotive body and chassis subsystems, digital power conversion, and USB-less consumer appliances that require CAN, UART, and SPI connectivity. The wide operating temperature range of -40C to +85C supports both commercial and industrial deployments.
When designing with this part, allocate at least one analog pin for Vcap decoupling and follow Microchip's recommended 10 uF + 0.1 uF bulk bypass topology to ensure core voltage regulator stability. Programmers should configure the JTAGEN fuse before relying on boundary-scan for production test, since boundary-scan is disabled by default to free the four JTAG pins for general I/O use.

Ghi chú thiết kế
Place a 10 uF bulk capacitor in parallel with a 0.1 uF ceramic on Vcap (pin 27) to stabilize the internal 1.8 V core LDO. According to the Microchip datasheet, insufficient Vcap decoupling causes POR misbehavior and Flash read errors under high CPU load. Each VDD/VSS pair also requires its own 0.1 uF local ceramic placed within 3 mm of the pin to minimize switching noise injection from the digital core.
Route the 20 MHz crystal traces (OSC1/OSC2) as short, symmetric, ground-shielded traces with the load capacitors placed within 2 mm of the IC. Avoid routing high-current switching signals (PWM outputs, triac drivers) parallel to the oscillator traces to prevent injection locking. Place the analog VDD/AVSS star-ground connection at a single point to keep ADC reference noise below 1 LSB at 12-bit resolution.
Do not forget to clear the JTAGEN fuse in the configuration bits if JTAG pins (PGEC1/PGED1) must be used as general-purpose I/O. By default, JTAG is enabled and four pins are reserved for boundary-scan testing. Configuring JTAGEN=OFF frees these pins for analog or digital I/O use, but disables in-circuit debugging through the JTAG interface. Use the ICSP interface (PGEC2/PGED2) for programming in production to retain general-purpose I/O access.
